HISTORICAL BACKGROUND

The initials "CB" are used by Americans to designate the Citizens' Band. This frequency band, which began to be used in the 50's, enabled American truckers to break the monotony of long distances and to get help when they broke down; hence, the spirit of solidarity this means of communication has always tried to transmit. At first, it was mostly used by truck drivers who, in introducing its principle, also created a special language based on Americanisms, contractions and coded expressions.

CB RADIOS: HIGH-PERFORMANCE TRANSCEIVERS

CB radios allow you to receive and transmit messages free. Several people can exchange remarks, at the same time, and on the same channel. This distinctive feature is the very basis of the CB spirit and results in conviviality and openness towards others. As opposed to telephones which work in duplex mode, conversations take place in simplex mode, in other words you must wait until the end of your correspondent's message before sending your own.

PRACTICAL INFORMATION

The use of CB radios is no longer subject to any license or tax today, the taxes being paid by the importer. It is, however, imperative to modulate with a radio which corresponds with the essential requirements of the European Directive R & TTE n° 1999/5/CE according to the standards EN 300433 and/or EN 300135: 40 channels 4W PEP AM/ SSB and/or 4 W FM. Transmissions are legally made on 40 fixed channels de 26.965 MHz to 27.405 MHz and, depending on the radio, on one or more of the following three modulation modes: amplitude modulation AM (the most commonly used mode in France), frequency modulation FM (communication over short distances of flat, open ground) and single side band SSB (communication over long distances, according to atmospheric conditions). These radios can be divided into three categories: "mobile" radios are designed to be installed in a vehicle. "Portable" radios are autonomous and have no exterior power supply. The term "base" is used for radios which are designed for use in a set place in a residence.

CB RADIOS AND SAFETY

CB radios are a means of communication for the general public, offering a wide variety of possible uses (leisure, safety, friendship, etc...), which have won acclaim. Today, CB's are recognized as being a factor which improves prevention and safety on roads. Certain organizations (fire departments, the Red Cross, associations,...) which have incorporated them in the process of initiating emergency aid, are continuously tuned in to channel 9, the safety channel, so that they can act on the first call from a CB radio. The other special channels are 27, which is a call channel, and 19, used mainly for directions by truck drivers and other road professionals to prevent accidents or traffic slow-downs.

ASC

THE SQUELCH

The squelch (or silencer) is a control found on all CB radio transceivers. This function is used to reduce background noise when there is no communication.

It is an adjustment which must be made precisely and repeated frequently in order to avoid reducing the reception capacities of the radio.

This is because the level of radio-electric background noise is not constant and varies according to the time of day and the geographical location.

In April 1996, Albert Bertrana, Technical Director of the Groupe PRESIDENT, presents to the specialized press an automatic squelch adjustment system called "Automatic Squelch Control" (ASC).

AUTOMATIC SQUELCH CONTROL

ASC continuously evaluates the received signal and existing noise. The signal/noise ratio determines whether a signal is heard or not. Applying surface mount package and microelectronic technologies, ASC uses more than 40 semiconductors, between transistors and diodes.

CB radios, which have always been a security element in vehicles, are now even more so since drivers will no longer have to make manual adjustments, or check the noise level, since ASC does this for them.
